Vulnerability in the Helidon product of Oracle Fusion Middleware (component: Imperative Web Server). The supported version that is affected is 3.2.18. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Helidon. While the vulnerability is in Helidon, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Helidon accessible data as well as unauthorized update, insert or delete access to some of Helidon accessible data. CVSS 3.1 Base Score 8.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N).
AnalysisAI
Unauthorized data access and partial data manipulation in Oracle Helidon 3.2.18's Imperative Web Server component allows a low-privileged attacker with HTTP network access to gain complete read access to all Helidon-accessible data and limited write capability. The vulnerability carries a scope change, meaning successful exploitation can cascade to impact additional products beyond Helidon itself within the Oracle Fusion Middleware ecosystem. …
